Answer 1

Answer:

• Gain.

Step-by-step explanation:

Given:

• A book seller sold 300 copies of books at a profit of 30%.

Find:

• If a book costs him Rs 15, find the total SP of the books.

Remember:

• 300 copies = 300 (15) = 4500

Using formula:

⇢ $\tiny{\sf{\underline{\boxed{\blue{\sf{ Profit = \dfrac{Cost \: price \times Profit \: percentage}{100} }}}}}}$

Calculations:

⇢ $\sf{\dfrac{4500 \times 30}{100}}$

⇢ ${\sf{\underline{\boxed{\pink{\sf{1350 }}}}}}$

Using the above value, we get:

⇢ $\sf{4500 + 1350 }$

⇢ ${\sf{\underline{\boxed{\pink{\sf{5850}}}}}}$

Therefore, 16800 is total selling price of the books.
